I could not, for the life of me, think of an original character. I literally sat thinking, searching various superhero pages etc, trying to be inspired, but nothing came to me, so i'm just going to go with a canon favorite of mine and just hope no one mimiced his power yet. I also felt he was a good choice as far as personality went, as the majority of characters seem to be rather 'nice'.
He won't be based on the comic version, however, as I know almost nothing about him in that state. Therefore if that doesn't sit well with you, then obviously you'll let me know.
Name: John Allerdyce
Appearance: 5'9" and average build with short chestnut hair usually slicked back or spiked up depending on his mood. His teal eyes always have a slight shimmer of mischief to them. He usually retains a serious and docile expression, but has an unmistakable arrogant smirk that surfaces often enough. He prefers dark or beige colored clothing, typical to that of a male teen with his personality. He always carries a Zippo lighter which he'll constantly flick open and light, much to the annoyance of others.
Personality: Overconfident, imperious and defiant are a few of many ways to describe John. While not overly rebellious or mischievious, he often is considered one of the more troublesome students at the school as he doesn't put much focus on his studies and prefers to mess around. This often shows in his actions also as he tends to be reckless and bold, which sometimes leans in his favor. His generally selfish attitude also doesn't make him the most cooperative teammate, but despite this, he is intelligent and when things do get serious, he can be an incredibly valuable ally. Even with this brash exterior, John isn't heartless, and at times may even surprise others with an act of kindness.
